IMPROVEMENT IN vSTEAiSd-DRYING'r GYLINDERS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, II. W.BU1TER\\'0RT1I, of Philadelphia,-Pennsylvania., have invented an improyed Bearing for Drying-Cylinders: :indd do hereby declare the following to be` afull, clear, and exact desc ription of the same.

My inrentiou consists of a. stand containing a. chamber, in combination with the tubular-spindle of a drying-I roller, and with a packing-ring and follower, the wholebeing constrlcted and arranged, as fully described 'here-4 after, so that the escape of steam-gn its passage from and to the cylinder isprevented. and so that the follower maybe adjusted without interfering with the operation ofthe machine. A

. Ivn order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation, reference being had to the accompanying drawing, which forms a part of'4 this specification, and in which- I y Y Figure 1 is avertcal section of my improved bearing for drying-cylinders.

Figure 2, an end view 'of threesome; and

Figure 3, a. vertical section of a'modification of my invention. l

A is a tubular spindle, a disk, a, pn whicll,is 'secured -to,oncend of a drying-cylindegb, shown. by red lincs.- A portion of the spindle is reduced in diamcter,an d ts snugly, but so ns to turn freely in the projection d of the hearing or stand B, andvn the vertical portion e of the latter is a passage, f, commnnicating with a chamber, It, into which the end of the tubular spindle .A projects; Between this projecting portion oi' vthe spindle and the interior of the chamber L is an annular recess for receiving a. ,packing-ring, z', and an annular portion, j, of a follower, D, radial arms projecting fromnths annular portion to a central hub, m, of the follower, and into this hub screws the end n'ot' the stud or set-screw E, a. collar, p, on which bears against the inside of a cap, F, bolted to the stand or hearing B, and enclosing the chamber D. A portion, q, of the std E passes through and 'is arranged' to turn in the cap F, the stud havnga square or other suitably formed end for receiving a screw-key or other likejnstrument, by which the s tud ca -n he turned and th'e follower forced against the pushing-ring,i so that the latter may form a perfectly tight joint round the tubular spindle'. In fig. 3 the stud E is oi' a different character, passing freelyA through, andV not turning in the hub m oi' the follower, against which, however, bears a nut, I', adapted to the .screw-thread on the stud, the cud of the latter fitting into a recess in the inside of the cap F, notpassng'throughthe'samo, as in tig. 1. The nut t is first adjusted to what may be considered the pro-per position on the stud, after which the cap is applied to its place, the actof tightening the c a'p forcing the follower against the packing. In eithcr'case V so tight a joint ismade round the 'tubular spindle that the steam, in its passage through the stand and spindle into the cylinder on one end of the same-,and from the cylinder through the stand at the opposite end, canuo't escape and damage the warp or other object on which `the cylinders have to be brought to bear. By'relnovingA lthe cap F ready' access may be had to the packing-ringe', while the follower may be adjust-ed by turning the stuJl'E, without the necessity cf opening the chamber It or inter'fering'with the operationof the machine.

I claim as my invention, and desire to sccurepby Letters PatentV V 1. The standard or bearing B, with its chamber h and` opening f, in combination wtth the tubular spinde A, projecting into the said chamber, a packing-ring, 2', and'y follower D, or itsequivalent, thewhole being constructed and arranged substantially as and for the purpose described,

2. The combination of the follower. D and a. screw-stud turning in the follower and projecting through the stand, substantially as and for the purpose set forth. v

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

H'. W. BUTTERWORTH.
